The bearded seal (Erignathus barbatus), the hooded seal (Cystophora cristata), and the ringed seal (Phoca fœtida), are northern species. See also Eared seal Harp seal Monk seal, and Fur seal, under Eared Harp Monk, and Fur. Seals are much hunted for their skins and fur, and also for their oil, which in some species is very abundant.

  • Interesting fact: The Navy SEALs were formed in 1962.
    • n seal A marine car nivorous mammal of the order Feræ, suborder Pinnipedia, and family Phocidæ or Otariidæ; any pinniped not a walrus—for example, a hair-seal, a fur-seal, an eared seal, of which there are numerous genera and species. Seals are regarded as carnivores modified for aquatic life. The modification is profound, and somewhat parallel with that which causes certain other mammals, the cetaceans and sirenians, to resemble fishes in the form of the body and in the nature of the limbs. But seals retain a coat of hair or fur like ordinary quadrupeds, and an expression of the face like that of other carnivores. The body is more or less fusiform, tapering like that of a fish. It is prone, and can scarcely be lifted from the ground, so short are the limbs. These are reduced to mere flippers, especially iu the true Phocidæ, in which the hind legs extend backward and cannot be brought into the position usual to mammals, but resemble the flukes of a cetacean. In the otaries (Otariidæ) the limbs are freer and less constrained. The latter have small but evident external ears, wanting in the former. The monk-seal, Monachus albiventer, lives in the Mediterranean and neighboring Atlantic, and a related species, Monachus tropicalis, is found between the tropics in Central American and West Indian waters. Another seal, Phoca cospica, inhabits inland waters of the Caspian, Aral, and Baikal. But with few exceptions all seals are maritime and also extratropical. They are especially numerous in high latitudes of the northern hemisphere. Among the Phocidæ may be noted Phoca vitulina, the ordinary harbor-seal or sea-calf, common in British waters and along the Atlantic coast of the United States; it is often tamed and exhibited in aquaria, being gentle and docile, and capable of being taught to perform some amusing tricks; it is one of the smaller species, usually from 3 to 5 feet long, and being the best-known, as well as wide-ranging, it has many local and fanciful names. Phoca grœnlandica (Pagophilus grœnlandicus) is the Greenland seal, or harp-seal or saddleback, peculiarly colored, of large size, and an important object of the chase. Pagomys fœtidus is a smaller species, the ringed seal or floe-rat of Greenland. Erignathus barbatus is the great bearded or squareflippered seal of Greenland, attaining a length of 8 or 10 feet. Halichœrus gryphus is a great gray seal of both coasts of the North Atlantic, of about the dimensions of the last named. Histriophoca is a genus containing the banded seal or ribbon-seal, H. fasciata or H. equestris. All the foregoing are members of the subfamily Phocinæ. Cystophora cristata is the hooded, crested, or bladder-nosed seal; this is a large seal, but the largest is the sea-elephant, Macrorhinus proboscideus, of southern seas; and these two genera form the subfamily Cystophorinæ. Certain seals of the southern hemisphere, of the genera Lobodon, Stenorhynchus (or Ogmorhinus), Leptonychotes (formerly Leptonyx), and Ommatophoca, form the subfamily Stenorhynchiæ; some of these are known as sea-leopards from their spotted coloration, and others as sterrincks. All the foregoing are Phocidæ, or earless seals, and they are also hair-seals. But the distinction between hair-seals and fur-seals is not, properly, that between Phocidæ and Otariidæ, but between those members of the latter family which do not and those which do have a copious under-fur of commercial value. The larger otaries are of the former character; they belong to the genera Otaria, Eumetopias, and Zalophus, are of great size, and are commonly called sea-lions; they are of both the northern and the southern hemisphere, chiefly in Pacific waters, and do not occur in the North Atlantic. The southern fur-seals or sea-bears are species of Arctocephahus, and among the smallerotaries. The fur-seal of most economic importance is the North Pacific sea-hear, Callorhinus ursinus. Some genera of fossil seals are described. See cuts under Cystophorinæ, Erignathus, Eumetopias, fur-seal, harp-seal, otary, Pagomys, Phoca, ribbon-seal, sea-elephant, sea-leopard, sea-lion, and Zalophus.

    • n seal An impressed device, as of a letter, cipher, or figure, in lead, wax, paper, or other soft substance, affixed to a document in connection with or in place of a signature, as a mark of authenticity and confirmation, or for the purpose of fastening up the document in order to conceal the contents. In the middle ages seals were either impressed in wax run on the surface of the document, or suspended by cord or strips of parchment, as in the papal bulls. (See bull, 2.) In some jurisdictions an impression on the paper itself is now sufficient, and in others the letters L. S. (locus sigilli, the place of the seal) or a scroll or a mere bit of colored paper (see def. 3) are equivalent. In the United States the seal of a corporation or of a public officer may be by impression on the paper alone.
